Java 如何在 Spring 中取消预定的 Quartz 作业

How to cancel a scheduled Quartz job in Spring

提问by Steve Neal

I'm using Spring to inject a Quartz scheduler (abstracted with Spring's TaskScheduler interface) into my app that loads jobs configured from a database at startup.

我正在使用 Spring 将 Quartz 调度程序（使用 Spring 的 TaskScheduler 接口抽象）注入我的应用程序，该程序在启动时加载从数据库配置的作业。

It adds each job in the scheduler something like this:

它将每个作业添加到调度程序中，如下所示：

TaskScheduler taskScheduler = ...;//injected    
Runnable runableThing = ...;
String cronExpression = ...; //from DB
taskScheduler.schedule(runableThing, new CronTrigger(cronExpression));

my question is this: Is it possible to specify something like a job_id that can subsequently be used to cancel the job/trigger - say in response to a user selecting the job to be cancelled in the web interface?

我的问题是：是否可以指定类似 job_id 之类的东西，随后可以用来取消作业/触发器 - 例如响应用户在 Web 界面中选择要取消的作业？

I've looked at the Spring docs and can't see a way to do this.

我查看了 Spring 文档，但看不到这样做的方法。

Any ideas gratefully received.

任何想法都非常感谢。

Unscheduling a Particular Trigger of Job

取消调度作业的特定触发器

scheduler.unscheduleJob(triggerName, triggerGroup);

Deleting a Job and Unscheduling All of Its Triggers

删除作业并取消调度其所有触发器

scheduler.deleteJob(jobName, jobGroup);

ScheduledFuture<V> job = taskSchedule.schedule(runableThing, new CronTrigger(cronExpression))
job.cancel(true);
